Abstract (en)
[origin: WO2009114955A1] The invention relates to an optical measuring element (1) for measuring forces in at least one direction. The measuring element has a single-piece structure (2) comprising an outside wall (3) and notches (4) introduced therein, wherein the notches (4) define more or less elastically flexible zones (5) in the structure (2) and constitute the only connection (6) between a first and a second region (7) of the structure (2). For optical distance measurements between the two regions (7) of the structure (2), one or more optical fibers (8) are each attached with one end (9) thereof to a region (7) of the structure (2) such that close to the ends (9) reflective surfaces (10) are located, which are firmly connected to another region (7). According to the invention, the optical fibers (8) are disposed on the outside wall (3). In addition, according to the invention each notch (4) comprises parallel edges (16).
